Application filed September 26, 1914. Serial No. 863,639.

T0 all,wkom z'zf may concern:

Be it known that I, MONROE GUETI, a citizen of the United States, 1esiding at Hartford, in the county of Hartford and State of Connecticut, have invented a new and useful -Improvement in Flexible-Conduit Fastei1erS, of Which the following is a spe ification.

It is more or less diflcult to bend and thru'st through the proper opehing in an outletb0x.fiexible conduit for electric Wires of the kind known as 100m, and When entered it ,quite frequently happens that after a time the end of such conduit, if too short, pulls out of the box, or if too long, Works into the box and occupiesneeded 'This invention relates to a tip Which is 'designed to be fastened to the end of a piece of flexible conduit of 100m type for the a neat end for the conduit and for holding that end in the desired relation to the Outlet box with which it is conneCted.

The object of the invention is to provide a tip of thischarcter which is very simple apply so that it Will grip the end of a piece -of conduit, Which is readily thrust through an opening in the outlet box, and When so thrust automatically fastens itself-in the opening so as to hold shows a side elevation of a flexible conduit er or tip Which embodies this inven- Fig. 2 shows a top view of the same.

Fig;3shows an end view; Fig. 4 illustrates one'df these tips being used -for fasteni'ng the end of a piece of conduit to the Wall of an outlet box.

The fastener is preferably made of thin sheet steel in the forn1of a cylinder 1 that is slitted along one side so that it may be opened and sprung onto the end of a piece of conduit. The base or inner end of this cylinder is provided with a fiange 2 that is somewhat larger in-diameter than the hole through. which the fastener is to be thrust.

The other end of thiscvlinder is preferablv out obliquely so that 1tmay be more eas ily W0rked doWn and thrust through the opening in the outlet box 3, When it is on the end of a piece of conduit 4. The cylinder is the conduit in the desired posi- Figure lof the accompanying drawings the flanged preferably slitted along' the short side. When the steel blank for this cylinder is shaped pointed teeth 5 are formed so that thev Will project inwardly and stick into the surface of the conduit on Which the fastener is sprung. These teeth are arranged in such manner that they will alloW the fastener to be slipped onto the end of the conduit but not Tongues 6 are stamxed from the blank so that they Will spring outwardly from the fastener. These tongues extend in such manner and their free ends terminate in position that when the fastener is thrust through the opening in an outlet box and the flange on the inner end is against the inner Wall of the box, the tongues Will spring out and engage the outer Wall of the box and thus hold the fastener in position, and, of course, as the teeth project clown into the conduit the end of the conduit is firmly held in place. As the cylinder which forms the fastener is slitted along one side it is easily spread open and closed upon conduit ofdif erent d1ameters.

. der that is slitted along one sid, has an outwardly extending flange at one end and that is cut obliquely at the other end, With teeth V projecting inwardly toward the flanged end of the cylinder,'and tongues wardly toward the fiange.

3. A conduit fastener comprising a cylinder that is longer on one side than the other projecting outand that has its shorter side slitted, said 03 1- 77 inder having an outwardly extending flange at one end, teeth projecting inwardly toward end of the cylinder, and tongues extending outwardly and oppcsing the flange.
